Solve the inequality:
3(4x + 9) + 5 > 7(8 − x)
Expand both sides: 12x + 27 + 5 > 56 − 7x 12x + 32 > 56 − 7x
Bring x terms to one side: 12x + 7x + 32 > 56 19x + 32 > 56
Subtract 32: 19x > 24
Divide by 19 (positive, so inequality direction stays): x > 24/19
Solution: x > 24/19 (approximately x > 1.263).
